I would recommend the B+W clear XS-pro. There is no need to use a UV filter as the sensor already has a UV coating. As for the ND filter, it depends on what you application is. For example, if you're using it for landscape, I would recommend a filter holder system like Lee because if you need grad ND filters, you can adjust the filter transition line precisely. If you're using it to cut down light for wide apertures, you could use a screw-in filter or a filter holder. The filter holder system is kinda versatile.
